海琴论坛预告第10期：中尺度phase resolving波浪模拟

报告内容简介：

Yang and Liu (2020, 2022, hereinafter referred as YL-models) presented two sets of depth-integrated wave--current models. The major difference between YL-models and other existing models is that the YL-models are based on the depth-integrated continuity equation and momentum (Euler’s) equations in terms of horizontal velocity components and free surface elevation. The vertical velocity component and the pressure field can be expressed analytically in terms of the horizontal velocity and the free surface elevation. In this talk a new model will be presented. In this model, the velocity profiles of the horizontal velocity components in the water column are discretised by finite elements. The model equations are general and can be applied not only to water wave propagation and scattering problems, but also transient and steady hydraulic flow problems.
